FRANK F. JEWETT, OF OBERLIN, OHIO,

BOTTLE-STOPPER.

SPECIFICATION formingpart of Letters Patent No. 276,822, dated May 1,1883.

Application filed November 2,1882; (No model.)

To all whom it may concern: i

Be it known that I, FRANK F. JEWETT, of Oberlin, in the-county of Lorainand State of Ohio, have invented a new and useful Improvement inBottle-Stoppers, of which the following is a full clear,'and exactdescription.

This invention, although applicable to hottles for various purposes, orrather for containing different substances, is more especially designedfor bottles used in chemical laboratories, including bottles used forcontaining various reagents and acid or corrosive liquids. It willaccordingly here be described more particularly with reference tobottles of the description or for the purposes herein last named. Thesebottles are usually fitted with two different kinds of stoppers, knownrespectively as the flat-headed stopper and the hood stopper. Both havetheir special advantages and both their peculiar defects.

The flat-headed stopper consists of a. taper plug orbody of circularform in its transverse section, mounted by a flatsided finger-piece orhead arranged-to project in line with the longitudinal axis of the plug.This form of stopper not only furnishes a good purchase by which thestopper can be loosened and turned when stuck in the mouth of thebottle, so that it requiresmore than ordinary force to remove it, but itis very easily and conveniently held between the second and third orother fingers of the inverted orupturned hand, while the same hand isemployed without inconvenience in holding the bottle to pour the liquidfrom it, leaving the other hand free to hold. another bottle or vesselinto which the liquid is to be poured, or for any other purpose. Suchform of stopper, however, has its disadvantages. .Thus its flat headdoes not protect the mouth of the bottle from dirt, caused by theaccumulation of dust about or around it, and which, in order to keep thereagent or liquid pure when pouring from the bottle,- must. be carefullywiped off. Such stopper, too,when removed and held inverted by thefingers, as above described, is apt to have a drop or more of thecontents of the bottleon it, and this, as in the case of an acid orcorrosive liquid, in trickling down, soils or injures the fingers.

The hood form of stopper consists of a like taper plug or body mounted,bya flat cover or disk which fits down moderately close to the mouth ofthe bottle and protects said mouth from dust; but the shape of suchcover or head does not present the same facility or purchase as theflat-sided head does for removing the stopper when stock; nor does itallow of the removal and holding of the stopper between the fingers bythe same hand which holds the bottle, but necessitates the removal ofthe stopper by one hifnd and the holding of the bottle by the other handand after the stopper has been removed it must of necessity, whenpouring from the bottle, be 6 laid down on any convenient surface, whichexposes it to being soiled, and, when reinserted, causing it to impairthe purity of. the reagent or other contents of the bottle; and here itmay be observed that in chemical lahorato- 7O ries it is veryimportantthat the purity of the chemicals should be preserved.

My invention combines all the advantages of thesetwo forms of stopperswithout the defects of either 5 and it consists in a bottle-stopperhaving its plug or body part mounted by a hood or shield arranged tocover the' mouth and outer end of the neck of the bottle, and having apendent flange arranged to fit outside of the rim or collar of the neckof the bottle, and this, again, surmounted by a [latsided head orfinger-piece, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, formingpart of thisspecification, in 8 which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 represents a partlysectional elevation of a bottle havingmyimproved stopper applied, the stopper being partly in section; Fig. 2,atop view of said stopper; Fig. 3 is a vertical section of the stopperand neck of the bottle, to which it is applied.

Referring to the drawings, the stopper is represented as havingits plugor body part a mounted by a hood or shield, 1), arranged to cover andpreferably extend beyond the outer rim, 0, of the neck of the bottle,and to fit moderately close to or over the mouth and neck, and isprovided with a pendent flange, 0, ar- [00 ranged to snugly but .nottightly inelose the rim or collar 0 of the neck of the bottle, therebymore effectually excluding dust from getting under the hood onto themouth of the bottle. Mounted upon this hood or shield 71 is a fiat-sidedhead, (I, in line with or parallel to the longitudinal axis of the plug.Such stopper affords all the protection that the usual hood-stopperpossesses of excluding dust from the mouth of the bottle, and at thesame time admits of its being manipulated as the ordinary flat-headedstopper is worked and held, and not only possesses all the advantages,as hereinbefore enumerated, of said flatheaded stopper, but theadditional advantage, when inverted, as it is held between the fingersafter being drawn from the bottle, of catching on the' hood or shieldany drip of acid or corrosive or other liquid that may have been takenup by the stopper from the bottle.

The plug or body portion a, hood or cover I), and flat-sided. head orfinger-piece d of this double-headed bottle-stopper are made of glassand in one piece.

Having thus described my invention, I claim as new and desire to secureby Letters Patent As an improved article of manufacture, abottle-stopper consisting of the body a, the hood or shield b, havingthe pendent flange e, and the flat-sided head d, all constructed in oneand the same piece, substantially as described.
